A survey of the landed endowment of Glastonbury Abbey before 1066, with a history of its estates. The early history of the religious community at Glastonbury has been the subject of much speculation and imaginative writing, but there are few sources which genuinely further our knowledge of Glastonbury Abbey in the Anglo-Saxonperiod. This has resulted in a lack of serious historical research and hence the neglect of an important ecclesiastical establishment. This study brings together the evidence of royal and episcopal grants of land and combines it with material from Domesday Book, to produce a survey of the landed endowment of Glastonbury Abbey before 1066, and an analysis of the history of its Anglo-Saxon estates. Although there is too little data to formulate a complete account of the Abbey's early landholdings, the surviving evidence, collected together here, outlines a history for each place named in connection with the pre-Conquest religious house; in addition, each case helps to establish an overall framework for the life-cycle of the Anglo-Saxon estate, building on our understanding of actual conditions of tenure and of the various fortunes ecclesiastical land might experience.
